Title: Hot melt adhesive prodn. - by pre-soaking polymers in melt in kettle, then pumping to second kettle while subject to high shear for very short periods
Inventor: CARDUCK FRANZ-JOSEF DR
IPC: C09J201/00
Filed: 1990-06-27
Abstract: Process is for mfr. of hot melt adhesives. One or more polymers are dissolved in a melt consisting of dispensing materials which are solid and/or liq. at room temp. Mixing is realised with a shear energy input of at least 0.002, pref. 0.005 Kwh per kg of material and mixing time is a max. of 5s., pref. less than 1s. Shear speeds are 10000-500000, pref. 50000-200000 S(-1). Combined high shear rate and short shear times enable almost all hot melt adhesives to be produced without viscosity redn.. Materials forming a dispensing melt are introduced into a first kettle in which the polymers are warmed and presoaked.  Heating and premixing of the product is achieved by pumping the mixt. via a shut-off valve, through a combined heat exchanger and static mixer, a further shut-off valve and back into the first kettle. USE/ADVANTAGE - To produce hot melt adhesives, has a shorter cycle time. Improves prod. quality.

Title: Turntable with stepwise drive -  has automatic locking device to hold turntable when not being driven
Inventor: ANGUE ERICH
IPC: B23Q16/06
Filed: 1990-09-11
Abstract: The turntable (2) for supporting workpieces on the work-table of a machine tool is rotated with a stepwise motion. The turntable (2) is rotated by means of a swinging arm (23) which drives a rod (22) which has a pin (25) at its outer end which engages a notch (4) in the rim of the turntable (2).

Inventor: WILLMANN KARL-HEINZ DIPL ING
IPC: B60T8/48
Filed: 1991-04-13
Abstract: The externally powered braking system is designed to remain operative if electronic components fail. The externally powered braking system (10) has a pressurising medium reservoir (22) from which a first line (29) with an electromagnetically operable valve arrangement (33) leads to at least one wheel brake (20). Parallel to it, a second line (39) with a mechanical brake control valve (15) operable by the brake pedal (13) and an electromagnetically operable check valve (41) runs from the pressurising medium reservoir (22). In addition there are a brake pedal travel pick-up (14) and, on the wheel brake side a pressure sensor (44) and a wheel speed sensor (55). When the brakes are operated, the control device (54) feeds braking pressure into the wheel brake (20) via the valve arrangement (33) and the check valve (41) adopts its blocking position. If the control device (54) fails, braking pressure is fed into the wheel brake (20) via the mechanical brake control valve (15) and the check valve (41). The externally powered hydraulic braking system is especially suitable for use on motor vehicles.

Title: Rotor spinner sliver loosening roller - has return of fibre build=up at end of spiral sawtooth clothing coils as drawn and oriented fibres
Inventor: SCHMOLKE KARL-HEINZ
IPC: D01H4/36
Filed: 1991-07-25
Abstract: At the end of the spiral of sawtooth wire round a sliver opening roller, for rotor spinning machines, collected fibre material which has been carried by the spiral path builds up at holes round the circumference. Part of the holes grasp the fibres and, while clamped, pass them to the final free row of sawteeth as drawn and oriented separate fibres to be fed to the fibre guide channel. The other part of the holes have a smaller cross section so that the fibres are taken into the drawing holes. The remaining air volume is taken out through the dust collection chamber and the gap between the loosening roller body and the bearing to prevent dust entry into the collection chamber. The capacity of the sawtooth clothing pref. continually increases in the advance direction of the spiral winding towards the end build-up zone, with wider and/or deeper zones between the coiled teeth rows, to reduce fibre build-up. The take-in table angle can be set so that the gap between it and the loosening roller is less at the fibre build-up side than at the opposite side, so that the fibre material is forced more deeply into the sawtooth clothing. ADVANTAGE - The action prevents fibre build-up on the roller, and ensures that the loosened fibres are drawn and oriented when they pass to the fibre guide channel to the spinning stage.
Patent DE-4125744-A1 (DE)
Title: Spark erosion process - comprises applying continuously increasing test voltage until test discharge occurs and initiating high current erosion discharge if this current is sufficiently high
Inventor: RUEHL FALK DR
IPC: B23H1/02
Filed: 1991-08-02
Abstract: In a spark erosion process, a test voltage is applied to the inter electrode gap at the beginning of a discharge cycle, which includes a pause and one or more high current discharges, and a high current erosion discharge is initiated at the end of the resulting test discharge depending on the test discharge current. The test voltage (UT) is continuously increased until a test discharge occurs and if the test discharge current (iT) variation per unit time is sufficiently large, the high current erosion discharge is immediately initiated. Spark erosion appts. for carrying out the process is also claimed. ADVANTAGE - The test discharge current allows differentiation of dielectric displacement current flow or resistive current flow so that the erosion discharge can be immediately initiated, thus increasing erosion speed and efficiency.
